A case of sphenoid sinus carcinoma of the right side representing Garcin syndrome has been reported. The present-case (34 year old male) was the 26 th case as Garcin syndrome, the 9th case as sphenoid carcinoma so far reported in Japan.
On rhinological surgery of sphenoid sinus carcinoma, most cranial nerve symptoms other than optic as well as trigeminal nerve symptoms have been improved. The maxillary nerve which is the second branch of the trigeminus traversing along anterior superior wall of sphenoid sinus, penetrating into intracranium towards trigeminal ganglion might paralized motor neuron just situating underneath. Therefore, trigeminal disturbances still remained after surgery could be referred to motor neuron involvement along with sensory neuron by carcinoma. On the other hand, optic nerve disturbance might be due to inflammatory changes often seen in mucocele as well as carcinomatous infiltration. Other cranial nerve symptoms which were recovered their functions by surgery were concluded to be rather carcinomatous neuropathy-certain reactive alterations of peripheral nerves originated by cancer than direct carcinomatous infiltration.
